20 Claims.

This invention relates to the provision of a novel and efiicient swing spindle attachment for application to spinning frames.

The swing spindle attachment of the present invention is particularly well adapted for application to a silk throwing machine such as illustrated and described in United States Patent No. 2,044,621 issued to me June 16, 1936.

It is the purpose and object of the invention to devise a swing spindle attachment designed to effectively and efiiciently cooperate with a stop motion mechanism of simple design. It is additionally an object of the invention to provide a swing spindle attachment embodying a positively actuated brake for the spindle whirl that is immediately applied upon initiation of movement of the stop motion mechanism.

Further and more detailed objects of the invention will become apparent as the description proceeds.

Referring to the drawing:

Figure 1 is a plan view of the novel swing spindle attachment conforming to the invention; and

Figure 2 is a view in side elevation with parts broken away.

Referring to the drawing, the spindle supporting rail embraces the two parallel spaced-apart tubular members I and 2. The swing spindle base is indicated generally at 3 and is held in fixed relation to the spindle rail bars I and 2 by the clamping members 4 and 5 that are clamped above and below the rods l and 2, respectively, through the medium of the bolt 6 having the clamping nut 1.

The base 3 is provided with an upstanding bearing member 8 adapted to be telescopically received within the cap-shaped bearing member of the swing 9. Additionally the base member 3 is provided at its forward edge with the upwardly extending wall Ill. The wall I is provided with a spring seat H and an adjustable spring seat screw 12. The swing 9 is provided with a downwardly extending arm l3, and the coil spring I4 is adapted to be positioned intermediate the spring seat II in the wall In of the base member 3 and the arm 13 of the swing 9. The spring 14 functions to normally force the swing 9 toward the belt l and cause the whirl 16 of the spindle I! to have driving engagement with the belt.

The end of the base member 3 opposite the bearing member 8 carries a pivotal support l8 for the stop motion rod l9. It will thus be observed that the stop motion rod 19 is adapted to swing outwardly with respect to the base member 3. (For the specific manner of movement of the stop motion rod 19, reference may be had to my issued Patent No. 2,044,621 and particularly to Figure 5 thereof.)

It is, of course, understood that the spindle ll with its whirl I6 is carried by the swing 9. The specific construction of the spindle and the whirl and their manner of mounting on the swing are more or less conventional and have not been disclosed in specific detail.

Coming now to the brake actuating means, it will be observed that the swing 9 is provided forwardly of the spindle with a projecting lug 2!). Threaded into the lug 20 is a pivoted bearing pin 2| on which is pivotally mounted a brake lever 22. The brake lever 22 carries the friction brake contact member 23 at one end thereof in position to be brought into contact with the whirl I6. The opposite end of the lever 22 is bifurcated as shown at 24 to receive the pivotally mounted stop motion rod [9. The small coil spring 25 functions to normally hold the brake member 23 disengaged from the whirl 16. The lug 20 may advantageously be provided with a stop member 26 which limits the backward movement of the brake lever 22.

The operation of the device is as follows: When the stop motion rod l9 is released because of the breaking of a thread, the stop motion rod l9 pivots about the pivotal mounting l8 moving outwardly with respect to the spindle bearing 8. During its initial movement, the rod ['9 actuates the brake lever 22 about the pivot bearing 2| and immediately effects a contact between the brake member 23 and the whirl I6. Further pivotal movement of the stop motion rod l9 acts to carry with it the swing 9, causing the same to pivot about the bearing 8 and to move the whirl l6 out of contact with the belt 15. It will be observed that the lever 22, after the brake 23 contacts with the whirl [6, becomes a rigid extension projecting from the free end of the swing 9. When the stop motion rod I9 is returned to normal position, the spring I4 acts to again return the swing 9 to operative position, i. e, with the whirl [6 in driving contact with the belt :5, and the spring 25 acts to release the brake 23 from the whirl.

The present invention provides a positive brake actuating means that insures immediate actuation of the brake during the first movement of the stop motion rod. In ring spinning operations where the spindles are operating at excessively high speeds, it is important that the spindle be stopped immediately after a break occurs in a thread. The mechanism of the present invention provides for the simple and expeditious attainment of this result through means that may be economically produced and installed. From the foregoing it will, therefore, be observed that I have devised a novel and efficient swing spindle attachment for spinning frames.

Having thus described my invention, what I claim is:
